Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SB1W01 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be SPDT
• Switch function must be On-Mom (momentary)
• AC current rating must support minimum 6A
• AC voltage rating must support minimum 125V
• DC current rating must support minimum 3A
• DC voltage rating must support minimum 30V

Mechanical & Physical Requirements:

• Mounting type must be Panel Mount, Rear
• Termination style must be Solder Lug
• Actuator type must be compatible with plunger or equivalent mechanism

Compliance & Regulatory Requirements:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) preferred for storage stability

The substitute parts listed below meet these core electrical and mechanical parameters, though variations in panel cutout dimensions, operating temperature range, and actuator appearance may exist and must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

MBN15SB1W01 (NKK Switches): This part maintains NKK Switches manufacturer continuity and active product status. However, critical electrical parameters (current and voltage ratings) are not specified in available documentation. This part is suitable only when detailed specification verification with the manufacturer confirms compatibility with the 6A AC / 3A DC and 125V AC / 30V DC requirements.

MPA106F (TE Connectivity ALCOSWITCH): This substitute meets all specified electrical requirements with 6A AC / 4A DC current rating and 125V AC / 28V DC voltage rating. The 28V DC rating is within acceptable tolerance of the original 30V specification. Panel cutout diameter is 6.35mm, requiring mechanical redesign if the original 12.50mm cutout cannot be modified. Active product status and ROHS3 compliance ensure long-term availability and regulatory compliance.

MPE106F (TE Connectivity ALCOSWITCH): This substitute provides identical electrical specifications to MPA106F with the addition of splash-proof ingress protection. The 28V DC rating and 6.35mm panel cutout diameter present the same mechanical considerations as MPA106F. REACH Affected status requires compliance verification for specific end-use applications. Active product status supports procurement continuity.

MPG106F (TE Connectivity ALCOSWITCH): This substitute meets electrical requirements with 6A AC / 4A DC current rating and 125V AC / 28V DC voltage rating. The panel cutout diameter of 11.80mm is closer to the original 12.50mm specification, reducing mechanical redesign requirements. Black button actuator differs from the original plunger design. Active product status and ROHS3 compliance are confirmed. REACH Affected status requires compliance verification.

Frequently Asked Questions (FAQ)

Q: Can MPA106F, MPE106F, or MPG106F be used as direct replacements for MB2011SB1W01?

A: These parts are electrically compatible substitutes meeting the SPDT circuit, 6A AC / 125V AC, and momentary function requirements. However, mechanical compatibility depends on panel cutout dimensions. MPA106F and MPE106F require 6.35mm cutout diameter versus the original 12.50mm. MPG106F requires 11.80mm cutout diameter. Panel redesign may be necessary.

Q: What is the significance of the 28V DC rating on substitute parts versus the original 30V DC rating?

A: The substitute parts are rated for 28V DC, which is 2V lower than the original 30V DC specification. For applications operating at or near 30V DC, this reduced margin must be evaluated against actual circuit voltage levels and transient conditions to ensure adequate safety margin.

Q: Why is MBN15SB1W01 listed as a substitute if electrical parameters are not specified?

A: MBN15SB1W01 is listed based on the provided substitute list and maintains NKK Switches manufacturer continuity with active product status. However, electrical parameter verification with the manufacturer is mandatory before selection for applications requiring the full 6A AC / 3A DC and 125V AC / 30V DC specifications.

Q: What is the difference between MPA106F, MPE106F, and MPG106F?

A: All three parts share identical electrical specifications (6A AC / 4A DC, 125V AC / 28V DC). MPE106F includes splash-proof ingress protection. MPG106F features a black round button actuator versus the plunger design of MPA106F and MPE106F. Panel cutout diameters differ: MPA106F and MPE106F require 6.35mm, while MPG106F requires 11.80mm.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts (MBN15SB1W01, MPA106F, MPE106F, MPG106F) are ROHS3 compliant. This ensures regulatory compliance for applications subject to RoHS requirements.

Q: What is the impact of REACH Affected status on MPE106F and MPG106F?

A: REACH Affected status indicates these parts contain substances of concern regulated under REACH. Compliance verification and documentation requirements apply for end-use applications subject to REACH regulations. MPA106F lists REACH status as Vendor Undefined, requiring clarification with the supplier.

Q: How do electrical life ratings compare between the main part and substitutes?

A: The original MB2011SB1W01 is rated for 25,000 electrical cycles. All TE Connectivity substitutes (MPA106F, MPE106F, MPG106F) are rated for 50,000 electrical cycles, providing extended operational life. This represents an improvement over the original specification.
